I think we have a problem with the literature. GR Osborn's study of coronary arteries of 109 adolescents was apparently first reported on in 1963 in his book The Incubation Period of Coronary Thrombosis (Butterworth, Kent, England, 1963) and this study was quoted in Pediatric Nutrition, Fima Lifshitz, ed. Marcel Dekker, New York, 1982, pp. 59-60, which is where I read about it. According to the chart on p. 59, the percentages are nothing close to the 1967 Osborn study that both Susan and Katherine wrote me about, and apparently it is the same study under discussion! The differences ARE significant and striking, but still..... my pedantic heart is all aflutter. As for the large English study by Fall et al., I found it in BMJ 304:801-805, 1992. Brace yourselves for this. There were 4 groups: (1) breast and bottle fed; (2) breastfed and weaned at 1 year; (3) breastfed and NOT weaned at 1 year; (4) bottle fed. MORTALITY RATE FOR ISCHEMIC HEART DISEASE WAS HIGHEST (97) IN GROUP 3, FOLLOWED BY GROUP 4 (95), FOLLOWED BY GROUP 2 (79), LAST WAS GROUP 1 (73). If someone can explain this to me, I'd be grateful. Groups 3 and 4 also had the highest levels of cholesterol and LDL cholesterol, but I'm OK with this. I would really appreciate it if a wiser and more experienced head would read this study, so I can find reasons explaining the somewhat strange results to my boss. Maybe smoking wasn't really controlled for? etc. I already made my first "presentation" and he sounded interested. He has a very big name in the wonderful world of cardiology, so if I can hook him, it would be good for our side. These studies are giving me insomnia. Judy Knopf
